CLAMP-BRACKET FOR SHADES AND CURTAINS.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed October 6,1905. Serial No. 281,575.

To 0.7] whom it nuty concern:

Be it known that I, CHARLES l/VILBER Moons, a citizen of the United States, residing at St. Louis, State of Missouri, have invented new and useful Improvements in Clamp-Brackets for Shades and Curtains, of which the following is a specification.

This invention relates to a clamp-bracket for supporting either shades or curtains for windows, or both shades and curtains, as may be desired; and the primary object is to provide a device of this class which maybe readily applied over a corner block or projection of a window-frame and embodying a construction conducive to a positive or iirm'application without relying on nails, spurs, or other defacing fastening means now commonly employed for this purpose.

A further object of the invention is to provide a bracket of the class set forth embodying an adjustable organization of elements to adapt it for application to corner blocks or projections of a window-frame having varying vertical extent.

A still further object of the invention is to so dispose the carrying device or devices for either the shade or curtains, or both, that the weight strain will be equalized and overcome any tendency of a-stronger drag orpull on one extremity than on the other, and thereby prevent loosening of the bracket after it is applied.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a front elevation of an upper portion of a window, showing the improved bracket applied thereto and supporting a shade-roller and shade and a curtain-pole. Fig. 2 is a detail perspective view of the bracket shown applied to a corner block or projection of a window-frame, illustrated in dotted lines.

Similar numerals of reference are used to indicate correspondingparts throughout both the views.

The numeral 1 designates a window-frame having upper corner-blocks or analogous projections 2. The bracket embodies a clamp member 3, having an upper angular end 4, which is increased in thickness to receive clamping-screws 5. A carrying member 6 is adjustably applied to the clamping member j 3 and, as shown by Fig. 2,has an outwardly- 1 projecting curtain-pole-carrying arm 7, and a window-shade-roller-supporting arm 8. In some instances the pole-carrying member 7 may be dispensed with, as will be obviously apparent, and the arm 8 alone used on the said member 6. In other obvious changes within dispensed with and the arm 7 alone used on the member 6. The member 7 iias slide devices 9 embracing the member 3, and in both members 3 and 6 are screw-openings 10, which are adapted to be brought into alinement to receive an adjusting-screw 11. By this means the two members 3 and 6 or the clamp-bracket as a whole may be lengthened or shortened, as may be found necessary, to accommodate the practical application thereof. The member 6 also has at its lower end an angular foot 12, which ooiiperates with the angular end 4 of the member 3 to effect a positive application of the bracket.

The arm 3 is formed with a curved recess 0r seat 13 in its upper portion to receive one extremity of a curtain-pole 14, as shown by Fig. 1, both brackets being similarly provided with the arm 7 in the preferred structure. The arm 8, as shown by Fig. 2, has an elongated slot 15 vertically disposed therein and increased in transverse extent toward its upper end, as at 16, to facilitate the insertion therein of the winding-stub 17 of the shade roller 18, which is inserted longitudinally therethrough and gravitates to the lower reduced portion of the said slot. The slot 15 is materially advantageous as compared to the usual or common form of slot opening outwardly through the upper part of the bracket, by reason of the fact that when the stub 17 is inserted therein it will be impossible for the shade-roller to become accidentally released and fall, as frequently occurs in the ordinary shade-brackets. Another advantage of the slot 15 having an increase in width toward its upper end is that the winding-stub may be inserted therethrough, even though it be set at a slight angle with respect to the slot. It will be understood that the arm 8, carried by the companion bracket, will have a circular opening therein to receive the roller-trunnion.

Both forms of the bracket will be constructed from suitable sheet metal, and the angular end or head 4 of the bracket has a greater extent than the foot 12 of the memthe scope of the invention the arm 8 may be ber 6. The purpose of this difference of extent in the parts just mentioned is to give a greater holding means at the upper part of the bracket, where the clamping-screws are used, than at the lower part of, the bracket, Where only a drawing tension is imposed. Screws24 will be used in the head 20, similar to the screws 5 of the bracket shown by Fig. 2; but the heads and feet of both brackets are entirely devoid of spurs or other fastenings, the clamping tension of the screws 5 and 24 being relied upon solely to hold the brackets in applied position.

In applying the improved bracket it is only necessary to move the head and foot thereof over the upper and lower edges of the corner block or projection of the window-frame and tighten the setscrews in the head. The members 3 and 6 will be first moved with respect to each other to accommodate variations in the vertical extent of the corner block or projection and secured by the setscrew 11. At any time desired the bracket may be detached from the window-frame, and in the use of the improved bracket marring or injury to any part of the windowframe is avoided, especially the facing of the frame. Furthermore, the brackets may be set apart any distance to accommodate variations in the length of shaderollers and corresponding. widths of shades.

It is proposed to construct the brackets in various ornamental contours at times, if desired; but in all changes care will be taken to preserve the simplicity and effectiveness in construction and operation. The bracket is j also strong and durable and may be expeditiously manufactured at a small cost.

Having thus described my invention, What I claim is 1. A bracket of the class set forth comprising overlapping slidable members, one mem-' ber having an angular head and the other an angular foot, said head and foot being integral with the parts of the bracket from which they project and the slidable members formed with registering openings longitudinally disposed in relation thereto and also provided with reversely-arranged embracing devices engaging the respective members, a clampingscrew for immovably securing the said members to each other, clamping-screw means engaging the angular head, and upper and lower supporting-arms integrally carried by one of the'members and adapted to hold a curtain-pole and shade-roller extremities.

2. A shade-bracket comprising verticallydisposed overlapping slidable members, the one member having an angular head and the other an angular foot, the head and foot being integral with the parts of the bracket from which they project, means for immovably securing said members to each other, clamping-screw means engaging the said angular head, and a supporting-arm integrally carried by one of the members.

In testimony whereof I affix my signature in presence of two Witnesses.
